Infrardeča termometri v ognjevzdržni rastline
Infrared thermometer due to its high accuracy of temperature measurement, is widely used in refractory factory, which is the key tunnel kiln, inside the temperature measurement point is more. Infrared thermometer has more temperature measurement points, continuous working time is long, such as temperature parameters are not well controlled, will bring significant economic losses to the production enterprise, therefore, the choice of appropriate temperature measurement means to ensure that the kiln is an important part of normal work. Tunnel kiln traditional temperature measurement method has two kinds: one is to use thermocouple temperature measurement, this method is characterized by high temperature accuracy, can connect the recorder or control system for closed-loop control, the disadvantage is the short life, especially in the high temperature kiln above 1300 degree its electric coupling consumption is very large, the price is also very expensive, the equipment running cost is high; ** kind of method is optical pyrometer, the method is based on the measured object luminous colour To measure the temperature, because it is not in direct contact with the high temperature area, so the service life is long, but the measurement accuracy is low, no electrical signal output, can not be automatically recorded, and human factors, the authenticity of the poor. Application of HD series infrared thermometer can effectively overcome the above shortcomings. The instrument has a high measurement accuracy (up to ± 0.5%), and can be like a thermocouple as the output of electrical signals, automatic recording and control, but also has a long service life (more than five years), easy to operate, human error and other advantages. Therefore, HD series infrared thermometer is an ideal temperature measurement instrument for high-temperature tunnel kiln.HD series infrared thermometer in the tunnel kiln application, according to the different requirements of the user, commonly used single-point temperature measurement and multi-point switching temperature measurement of the two programmes. They are introduced as follows:
Single-point temperature measurement system: each temperature measurement point using a probe and an instrumentation box, temperature measurement unit for temperature collection. The temperature measurement unit for temperature acquisition, and then the unit instrumentation box output 4 ~ 20MA analogue signal connected to the multi-point recorder or control actuators, but also through the RS-232 port and computer, printer and other equipment for data communication. The temperature measurement unit in this system is usually selected with high precision and strong function of HDIR-2A type instrument.
Preklapljanje temperatura meritev sistem: the sistem is nameščeno v temperatura meritev točka of infrardeča sonda signal is povezana do a HDMU-2}%tip večtočkovni termometer za signal obdelava. In o,2c the izhod in the temperatura meritev točka ustrezanje do the 1 ~ 5V temperatura signal za večtočkovni snemalnik zapisi, but tudi neposredno sko sko the RS232 vrata temperatura podatki v računalnik, the računalnik analiza in obdelava, but tudi lahko be povezani v tiskalnik neposredno na tiskanje izhod the temperatura podatki.
The zgoraj dva programa sta, enotočkov temperatura meritev sistem due do vsak temperatura meritev točka has an neodvisna temperatura meritve in signal obdelava sistem, its izhod modal in digitalni signali so realni čas neprekinjeni signali, hitro odziv hitrost, can be usede as a nadzor aktuator realni čas nadzor signali, in vrsta dosega zaprta zanka nadzor. Večtočkovno preklapljanje temperatura merjenje sistem, the izhod of analogni signal, čeprav tudi neprekinjeno, but tam je a gotovo lag z the real-time temperatura vrednost, it can only be used as a podatki pridobitev zapis, but not primerno as a control signal, the prednost of njegov stroškovno učinkovito, in uporaba manj zahtevna priložnosti lahko zmanjšanje oprema stroški.
V drugo ognjevzdržno ognjevzdržno peči, tak kot obrnjeno plamen peči in prizmatično peči in drugo priložnost zapadlo do uporaba temperatura meritve točke manj, so uporaba uporaba enotočkov temperatura meritev program več.
